I had a problem a few months back, i needed to have internet over wifi, since i used a PPPoE dialup it was not that easy, but i have found a solution. ( because i live in a commune we all have our own dial up)

now i get my dialup PPPoE on one lan card, and push out on the other to my router (turn DHCP off) and i can connect my Blackberry; ipad and laptop without sharing my data with other people.
